``python -m http.server`` no longer allows terminal control characters sent
|
|
within a garbage request to be printed to the stderr server log.
|
|
|
|
This is done by changing the :mod:`http.server`
|
|
:class:`BaseHTTPRequestHandler` ``.log_message`` method to replace control
|
|
characters with a :samp:`\\x{HH}` hex escape before printing.

The implementation of the typing module is now more resilient to reference
|
|
leaks in binary extension modules.
|
|
|
|
Previously, a reference leak in a typed C API-based extension module could
|
|
leak internals of the typing module, which could in turn introduce leaks in
|
|
essentially any other package with typed function signatures. Although the
|
|
typing package is not the original source of the problem, such non-local
|
|
dependences exacerbate debugging of large-scale projects, and the
|
|
implementation was therefore changed to reduce harm by providing better
|
|
isolation.

earlier work by Alexander Belopolsky and Matthias Braun.
